The T-U series comes from LEDEdit 2026: the same chip support in four sizes, from one output to eight. LEDEdit Pro 2026 includes all four models with 15 export-ready chip profiles each — including RGBW and DMX512.
Choosing a model
| Model | Outputs | LEDs per output | Total in profile |
|---|---|---|---|
| T1K-U-2048 | 1 | 2,048 | 2,048 |
| T2K-U-1024 | 2 | 1,024 | 2,048 |
| T4K-U-1024 | 4 | 1,024 | 4,096 |
| T8K-U-1024 | 8 | 1,024 | 8,192 |
Pick by how your cables run, not only by total LEDs: a sign with four separate letters is easier to wire on four outputs than as one long chain.
RGBW, 16-bit and DMX
- RGBW: TM1914, TM1814 and SM16704 profiles send a white channel as well.
- TX5806 uses a 48-bit RGB payload (16 bits per colour).
- DMX512 profiles at 250K, 500K and 750K.
Example: a T8K-U-1024 facade
Eight windows, each outlined with 1,000 pixels on its own output: 8,000 LEDs, every output at 1,000 of 1,024. In the LED Layout Creator draw each outline on p1…p8 and let Layout Check confirm the counts.
Chip profile notes: WS2811 / WS2812B
Each T-U model lists WS2811 as 1 of its 15 chip profiles (alongside WS2818B for the double-signal variant) — single-wire 800 kHz, 24-bit RGB. Use WS2811 for WS2811 pixels and for most WS2812B strips on this family (the same timing); WS2818B is the break-continuation variant. Set colour order GRB for WS2812B, RGB for WS2811 — swapped reds/greens means wrong order, not wrong chip — see wrong colours fix. For RGBW pixels pick TM1914 / TM1814 / SM16704 (each T-U model has 3 RGBW-ready profiles) and for DMX fixtures use DMX512 250K/500K/750K. The remaining profiles are SM16703, UCS1903, P9883, GS8206, 1916, TM1926, TX5806 (48-bit RGB). All 15 are export-ready per data/lep_controllers.json families ledit2026_t1k_u_2048 … ledit2026_t8k_u_1024.
5-step export to SD card (T-U series)
- Choose the right T-U size — Count cables, not just LEDs: 4 separate letters → T4K-U-1024 (4×1,024), 8 window outlines → T8K-U-1024 (8×1,024). In LED Layout Creator set Max LEDs/port to 1,024 (or 2,048 for T1K-U-2048) and place each outline on its own port.
- Animate per window — Build layers per output, add chasers or Auto Animate bursts, and preview with per-LED preview (demo in video tutorial).
- Pick chip — Output → Export LEDEdit .led → choose family T8K-U-1024 (or T1K/T2K/T4K-U) + chip WS2811 for WS2812B strips, TM1914 for RGBW, or DMX512 500K for DMX. Set colour order and FPS.
- Preflight & write — The dialog shows 8 outputs with 1,000 LEDs each, scenes and FPS. Export and Write to SD Card or copy the
.ledpackage to the card. - Test — If a window stays dark or colours are swapped, see last LEDs dark, wrong colours, and SD-card not playing. For legacy hardware, fall back to DXF + AVI.
FAQ
Which T-U model do I need?
Match cables: 1 cable → T1K-U-2048 (1×2,048), 2 → T2K-U-1024 (2×1,024), 4 → T4K-U-1024, 8 → T8K-U-1024. Each has the same 15 chip profiles.WS2811 vs WS2812B on T-U — which chip entry?
Use WS2811 for both on this family (800 kHz single-wire). Set GRB for WS2812B, RGB for WS2811. If colours are swapped, flip the order — wrong colours fix. For double-signal WS2818B pick the WS2818B profile.Do these support RGBW or DMX512?
Yes — 3 RGBW profiles (TM1914, TM1814, SM16704) and 3 DMX512 speeds (250K/500K/750K) per model, plus TX5806 48-bit RGB.Related guides

- Map your LEDs in the LED Layout Creator or import a DXF layout, with one port per controller output.
- Build the show with layers, clips and scenes on the timeline.
- Open Output → Export LEDEdit .led…, choose the T1K / T2K / T4K / T8K-U family and the chip type of your pixels.
- Check the preflight (controller, chip, colour order, scenes, frame rate, outputs, LEDs) and click Export.
- Copy the files to the SD card, or use Output → LEDEdit Tools → Write to SD Card….
